Customer Question

I have a 1996 Seabring convertable 2.3 that starts to misfire only after it gets up to running temp.I have put on a new catalytic converter,crank sensor,air temp sensor,map sensor,distrebutor,cap plugs & wires.I am out of ideas.What could be my problem?

If it's an actual misfire you're feeling, considering everything you've ruled out the most likely causes would be injector related or possibly cylinder sealing issues. You could have a valve or spring issue, which really shouldn't be temperature related, or you may have an injector going down due to an internal failure, wiring issue or failing driver within the powertrain control module.

The first step in diagnosing the problem is checking for fault codes. Do you know what codes are setting?
